VESA Dimensions is the most important specification when considering the best bracket for your TV. Please double check your TV is compatible with this bracket's maximum VESA (400mm x 400mm) by checking your TV's manual or by measuring the distance between the 4 holes on the rear of your TV.

Hi, I really wouldn't want to categorically say it would be fine. Personally I'd fix the bracket to the studs or as I did for my install I cut out a section of plasterboard and fixed some timber to the nearest stud. I then refixed the plasterboard. It sits behind the TV so I can't see the cut marks and next time I decorate I'll fill the cracks and paper over them.

There are many fixing holes along the frame so you will be able to secure it at 400mm centres.
I have just measures my TV and there is 50mm clearance from the rear of the TV to the wall so i would expect that to be enough for the coaxial cable to come out and turn.
